- Global or scene variables can be used with a unique action and condition. - Object variables can be used with a unique action and condition. - Variables need to be declared following the same logic as the new expression syntax. - Local variable can be declared on events - Extensions have their own variables - Show a diagnostic report when a preview is launched and there are missing scene variables, object variables or behaviors. - This is especially useful if external events are shared between several scenes.
